There was extensive coverage on TV, radio and in the press, with cover stories on several of the actors. For example there was an entire issue of Empire and a special Sunday Times supplement dedicated to the film. Warner Brothers had all the key cast members working hard.

It's not important and it's a diversion from the thread's topic but it's interesting to see people's perceptions of the marketing. I work in the media so am maybe more attuned to noticing the campaign.
